Abstract
Several embodiments of scalable image processing systems and methods are disclosed herein whereby color management processing of source image data to be displayed on a target display is changed according to varying levels of metadata.
Claims1
A method to encode image data with a processor, the method comprising:
- receiving image data and two or more sets of metadata associated with the image data;
- encoding the image data and the two or more sets of metadata to generate a bitstream;
- and
- transmitting the bitstream to a decoder with a target display;
- wherein:
- a first set of metadata describes characteristics of a reference display comprising:
- a) a white point for the reference display, and
- b) three primaries for the reference display,
- a second set of metadata describes video characteristic of the image data and includes at least a maximum luminance level of the image data;
- and
- a third set of metadata indicative of ambient light conditions for an environment of the reference display during encoding of the image data on the reference display, wherein each set of the metadata is separately partitioned in the bitstream and can be encoded independently of each other.
